Powder Coating

DB Sheetmetals has three powder coating booths and one wet spray booth, which allow us to spray items up to 2500mm long. Paint pre-treatment is done via a phosphate wash machine.

With a raft of colours in stock and standard colours delivered within two working days from our suppliers, we can meet the required delivery dates of the customer.

Small to medium sized items are cured using the camel back oven and larger items using the box oven; giving DB Sheetmetals the flexibility it needs to meet the customer’s needs.

Assembly of products can be carried out after painting and can be packed to the customer’s specification, bespoke boxes can be supplied if needed and printed labels are not a problem.

We can deliver nationwide using our own transport ensuring the product is delivered without any issues.

Powder application processes

The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a negative electric charge to the powder,
which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the work piece by the powerful electrostatic charge. There are a wide variety of
spray nozzles available for use in electrostatic coating. The type of nozzle used will depend on the shape of the
work piece to be painted and the consistency of the paint. The object is then heated, and the powder melts into a uniform film, and is then cooled to form a hard coating.

The wash plant uses the latest technology in phosphate washing. The phosphate front loading machine consist of a three stage cycle; hot washing with a phosphate solution, hot rinsing and then hot
passivation solution.
